Red-orange skies appear to be ablaze in Maria Calandra’s landscape painting of Weir Island in Maine while her blue skies over Como, Italy are a tranquil color but feature roiling clouds. Apocalyptic in their color and Mannerist in their elongated forms, Calandra’s paintings at Fredericks & Freiser Gallery are hallucinogenic visions that offer visual pleasure via their dynamic fluidity. Here, Mont Sainte-Victoire, made famous by Paul Cezanne’s many images of the mountain near Aix-en-Provence, rises above a field of flowers and greenery that appears to be flowing up the mountain. (On view in Chelsea through April 13th.)
